From: Ben Skeggs Date: Mon, 30 Apr 2012 16:33:43 +0000 (-0500) Subject: drm/nouveau: create real execution engine for software object class X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=20abd1634a6e2eedb84ca977adea56b8aa06cc3e;p=~shefty%2Frdma-dev.git drm/nouveau: create real execution engine for software object class Just a cleanup more or less, and to remove the need for special handling of software objects. This removes a heap of documentation on dma/graph object formats. The info is very out of date with our current understanding, and is far better documented in rnndb in envytools git.
